systemverilog generate用法 SystemVerilog中的generate指令是一种预处理指令,用于在编译时生成和实例化硬件描述代码。它可以根据特定规则和条件灵活地生成不同结构的硬件设计,从而提高设计的可重用性和灵活性。generate指令可以在模块或工作区内使用,可以根据布尔表达式、整数表达式和循环等条件来控制生成的代码块。 generate...

The DPIassertionblock checks whether its input signal is zero. Use this block to check that your Simulink®testbench behaves as expected by creating a Boolean expression and connecting it to the block. Generating SystemVerilog creates an immediate assertion in your generated module. Use this block...
A generate block allows to multiply module instances or perform conditional instantiation of any module. It provides the ability for the design to be built based on Verilog parameters. These statements are particularly convenient when the same operation
下面将介绍一些SystemVerilog Generate的常见用法。 1.条件生成:在generate块中可以使用if语句来生成不同的硬件结构。例如,可以根据参数值来选择是否生成某个模块实例,或选择不同的寄存器位宽等。条件生成可以通过命令行参数或宏定义来控制。 2.循环生成:使用for循环可以生成多个重复的结构或模块实例。例如,可以生成一个...

仿真的时候B没有问题,但是A会报错。 原因是,宏展开先于generate。在展开的时候方括号还在,但是反引号会消失。反引号消失之后变量无法识别,所以报错。
